Workers clean up after after a man committed suicide by jumping off the second floor inside the Staten Island Mall on Tuesday.

An 84-year-old man stepped onto a chair to lift himself over a second floor railing at the Staten Island mall Tuesday, and then leaped to his death, officials said.

The man, whose name was not immediately released, scaled the railing with a chair he took from the nearby food court, before he plummeted one story inside the New Springville shopping mecca about 11:15 a.m., cops and witnesses said.

He landed in front of a Gap store, horrified witnesses said.

"He was lying face down, covered in a pool of blood,” said one food court worker, who would only identify herself as Tommy. “People were gathering around him. Nobody was really saying anything, but the crowd kept getting bigger."

Other food court workers described the terrified reaction of shoppers.

"I just heard a thump, then people were screaming, kids were screaming," said a food court worker who wished not to be named.

The victim was rushed to Staten Island University Hospital, where he died, cops said. He did not have a note on him.

“I go to footlocker and see a suicide at the Staten Island Mall,” witness Joe Pitta tweeted from inside the mall.

The victim was taken to Staten Island University Hospital North in critical condition, officials said.

The shopping center was teeming with middle and high schoolers celebrating their last day of school, witnesses said.

“My 14-year-old daughter called me hysterical crying and told me that she had just witnessed someone commit suicide,” one woman, who would only identify herself as Teresa, told the Daily News. “She kept saying ‘Come get me! Come get me! I don’t want to be here.’ So I raced over and picked her up.”

“She caught it in the corner of her eye,” Teresa said. “At first she thought someone had thrown a bookbag over the railing, but then she looked and saw this guy covered in blood.”

Her daughter was too shaken to talk to reporters, Teresa said.

“It was the last day of school ... it was supposed to be a fun day,” she said. “Now she’s asking me ‘Why did he have to do that in a public place?’ I have to try and explain to her that we live in a crazy world.”

In April 2009, a depressed woman jumped 60 feet to her death at the Queens Center Mall, landing on a teenager relaxing in a massage chair. The teen suffered a gash on his head but survived.
